Marathon runner's Jozef Urban's penis pops out at race's climax

After months of training and preparing to run a marathon, a European contender will remember his athletic achievement for all the wrong reasons.

European man Jozef Urban's private parts have gone viral, after he accidentally flashed spectators in his sprint to the finish line.

Both his penis and testicles popped out of his shorts, as he bounded along to end the race, seemingly unaware of his display - or simply unfazed.

The runner even picked up speed towards the end, as the crowd laughed and cheered him to finish the race in a personal best time.
